Researchers have developed new methods to defend against and exploit backdoor attacks in advanced AI models. One approach, BYORn, aims to improve the robustness of large vision-language models by identifying and replacing semantically implausible responses generated during fine-tuning, thereby preserving clean task performance. In parallel, a new attack called SILENTDRIFT targets vision-language-action models used in robotics, exploiting action chunking to create stealthy backdoor attacks that are visually indistinguishable from legitimate demonstrations.
